A cron workflow is a type of workflow that is scheduled to run at specific intervals, similar to how cron jobs work in Unix-like systems. It allows you to automate the execution of workflows based on a predefined schedule, which can be expressed using cron syntax. Cron jobs are always scheduled in UTC timezone.

The cron job can be scheduled be passing the execution_configs in the workflow decorator

from truefoundry.workflow import workflow, ExecutionConfig

@workflow(
    execution_configs=[
        ExecutionConfig(
            schedule="*/10 * * * *",
        )
    ]
)
def your_workflow():
    ...

As you can see we have defined the execution config where the schedule is set to run every 10 minutes. The expression is define in cron expression format.
